time, with a view of poisoning or destroying` the boll weevil orother insects.

One of the objects of the invention resides in the provision of a machine of the above mentioned character, which is eX- trem'ely simple in construction, so that it can be manufactured and sold at a nominal cost, and consequently within reach of the average farmer. the machmebeing also very light to enable it to be easily and convenientlyy carried by the shoulders of two persons,

In carrying out the invention, I provide a manually operable fan or blower for forcing` the poisonous substance from va suitable'` hopper, through a number of flexible con- 'y duits the latter being provided with spray Y manner that will not require the use ,of the nozzles at their'ends, so that the poisonous substance is sprayed upon the plants to" destroy boll weevilor other insects. ,l The nature and advantagesof the invenlowing detailed description is readkink connection with the accompanying drawings7k the invention residing in the construction7 combination and arrangement of parts as claimed.

The ymachine forming the subject matter ofy my invention comprises a Jframe like structure adapted to be carried upon the shoulders of two persons. Consequently, they frame includes spaced parallel members 10 and 1l respectively, which may be of any suitable length and constructed from` any suitable material, these members being connected together by transverse strips 12. Depending from the members 10 and 11 at ak point approximately midway between the ends of said members is a substantially rectangular frame-like structure indicated generally at A. and including corner uprights 13 connected by transverse members 14. The

frame A is braced by the'reinforcing kelelments 15 which are connected with the corners of the frame A and withthe' members 1() and 11 respectively. Connected with the members at the opposite end of the frame and adapted to surround the bodies oi' the persons supporting the machine, and suspended from the members 10 and' 11 are y strapsl? and 18 adapted to 'go around the shaft and back of the user. The straps 17 and 18 at the opposite ends of the yframe serve' to support the machine upon the shoulders ofthe two persons using the same in a hands of the persons'to prevent the machine from slippingV or moving laterally upon the Arranged within the frame A is a. hopperl 2O which may be of any 'desired'capacityn and which'hopper'contains the powder or other .poisonoussubstance with which they plants are to be'sprayed. rCarried by thev frame immediately beneath the hopper 2O is a tan'or blower 21` which ycommunicates kwith the bottom ot' the hopper by means oi' a pipe 22 and projecting 4from the tan or blower k21 is a plurality of flexible conduits 23. the latter projecting in the direction of the torward 'end of theitrame andsupported in flex-l vvible loops 24 suspended from a cross rod 25 connected to the parallel members v10 and ,11.

The poisonous substance gravitates into vthe l fan or blower '21, and is'forced therefrom through the flexible conduits 28, at the outer endso whichv nozzles 26 are provided so that the Apurpose hereinaboveV mentioned.r The conduits 23' can be flexed so as to spray the poisonous substance in any desired direction, it being apparentv that the weight of these conduits is borne by the loops 24. The slide `said substance is sprayed over the plants for f valve 28 controls the communication between the hopper 2O and the pipe 22 o t the lan 2l, and this valve is equipped with a rod 29 which is disposed within convenient reach of one of the operators.

er drive shaft 8O is journaled in the members l and il, the opposite ends or this shaft being equipped with crank handles 3i extending in opposite directions, through the instrumentality ot which the shaft 30 is rotated. A. counter shait 32 is mounted for rotation with and arranged in parallelism with the shaift 30. .larger gear 33 is iixed upon the drive shaft 30, connected with a small gear 34 lixed upon the counter shaft 32, so that the latter mentioned shaft is rotated by the drive shaft 30. A. pulley 35 is carried by the counter shaft 32, and vover this and a pulley ,36 carried by the tan shaft 37 is trained an endless belt 38 which drives or operates the tan upon rotation of the drive shaft 30. A shaft 3S) is journaled upon the trame A, this sha-tt being passed through the hopper 2O and carrying an agitating element Ll() which when rotated aids thepoisonous substance in dropping from the hopper through the outlet opening in the bottom thereof. rEhe shatt 39 projects beyond. one side of the frame and is fitted with a sprocket ll. @ver this sprocket and a sprocketl2 carried by the drive shaft 30 is trained an endless chain 43 torimparting lrotation to the shaft 39 as will be readily understood.

In practice,the members and 1l of the machine are supported upon the shoulders of two persons arranged ione behind the other, and the machine held thereon by means ot the straps l? and 18 respectively. The person supporting the rear end of the machine operates the crank handles 31 in order .to rotate the drive shaft il() trom which the fan 2l and the agitating element Ll0 are actuated in the manner above described. The valve operating rod 29 is disposed in convenientl reach. or' this person and consequently the val-ve canbe regulated to permit ot the discharge of any particular quantity of the poisonous substance from the hopper to the Jfan casing 2l. As the shaft is rotated, the poisonous substance passes from the hopper 2O into thefan casing. the tan in turn forcing this substance through the lexibleconduits 23 to be sprayed through the nozzles, 26 uponthe `plants as above described. The supporting structure as well as theother parts of the machine are as lightv as possible, so as to be conveniently carried upon the shoulders of the users. It will be further noted that the flexible conduits 23 may be liexed and, arranged in any desired position to direct the spray or` they may be convenientlyhandled tor this purpose by the person supporting the machine at the forward end thereoif. The kconstruction and arrangement is such. that the velocity of the poisonous substance leaving the tan will not in anvr;Y affect the distribution which will be eqiial in each and every one oit the conduits employed.

'While from the foregoing' description the nature and advantages oit my device will be apparent, l desire to have it understood that i do not limit myself to the details ot construction herein shown and described, as `such changes may be resorted to when desired as fall within the scope of what is claimed..` f

Having described `the invention what is claimed is f l. A powder duster comprising a sup porting` structure having spaced horizontal members forming shoulder-straddling supports and frame depending from the said members yapproximately intermediate `opposite ends thereof, and

`powder distributing means supported in the dependingframe, said means being operable from one end ot. the frame and directed in operation from the other end.

2. A powder cluster comprising a supporting frame, powder spraying means supported in said frame, shoulder bars at the iront and rear ot the frame tor `projections across the shoulders ot the carriers, andv body-embracing straps depending from each pair ot shoulder bars.

3. A powder duster comprising a carryiup,` structure including arelatively vertical frame and horizontal carryingk members projecting beyond opposite; sides of the frame to provide shoulder-straddling bars adjacent theupper end,` apowder spraying mechanism supported in said frame and including flexible sprayers,` means operable from one side ot the trame for actuating the spraying mechanism, and loops depend'- -iug from the shoulder bars on the opposite side ofthe frame for supporting the noze Zle ends of the said `flexible sprayers.

4f. A powder` duster comprising a powder spraying mechanism, a pair of inflexible ymembers L.presenting asupport from ywhich the saldspraymg mechanism 1s suspended,

said members being extended beyond the same to provide shoulder-straddling-exten sions, and bodiy-encircling straps depending trom-the ,said extensions for securing the `latter in position upon the: shoulder.

In testimony whereof `I affix my signature.
